Be it known that I, Josnrir Hunn'neenn, of the city and county of .SanFrancisco, State ofCaliments in Explosive Oompoundsfand I do herebydeclare that the following description gives a full and clear statementoft-he names and quantities of the ingredicnts'used, with fulldirections for making and using the same. V i 7 My invention relates tocertain dilueuts or --=.ng|-e-, dients which I employ for mixing withand incorpo be manntacturedby the combination of chlorate of potash withsulphur, sugar, phosphorus, prussiate of eter, with the addition of Inthis compound ihur oxides are used, one or more of them can be dispensedwith, if desired; and

and in each case a powerful, and when sufliciently.

diluted with fatty, oily, or resinous substances, a per: j fectly safepowder to handle will be obtained.

The following. table will show a number of com-' pounds in which theoxides can be employedto ad} part; oxide of zinc, one (1) i is theaddition of one or more of the'mineral oxides in varyingproportions tothe compounds or mixtures above mentioned.

I prefer the oxides of ter. being especially preferable for use inblasting-powder which is to be employed in deep shafts, as it givesoif-nosmell and very little smoke.

Any of the mineral oxides, when thus employed, oil, when heated, asupply of oxygen, which gives hen givesa quick and powerful explosion,especially w the powder is confined. I :For a better explanation I addhereto a number of compounds, upon which careful and elaborate expel-iments have been made.
